[jsword-devel] Module Format

[Joe Walker]

Thanks, I'd not even seen the %.

I remember something like 7 years ago when I moved from C to Java 
feeling like everything looked the same, but for some reason I couldn't 
feel the ground under my feet any more. I guess I'm just having to learn 
to think in memory maps again.

There are just so many things like multi-value return types and pointer 
arithmetic that make this conversion hard. It'll be good when I can get 
back up to speed again.

Joe.
